Final answer:
A modified radical mastectomy involves the removal of the entire breast and most axillary lymph nodes, leaving the chest wall muscles intact. Surgery is a common treatment for localized solid cancers such as breast cancer, often involving removal of the tumor and lymph nodes.
Step-by-step explanation:
The correct explanation for a modified radical mastectomy is that it involves the removal of the entire breast and most axillary lymph nodes, but it preserves the chest wall muscles. This means that option (a) is correct: The entire breast and most axillary lymph nodes will be removed.
Surgery is often used to treat various types of cancer, including breast cancer. It aims to remove the cancerous tissue along with some of the surrounding healthy tissue and lymph nodes to help ensure that all of the cancer has been taken out. A biopsy is sometimes performed on the lymph nodes removed during the mastectomy to determine if the cancer has spread to these areas.
The breasts consist of mammary glands and fat, which have lobes and ducts important for feeding a child. The size of the breast is not indicative of cancer risk or complexity when it comes to surgery. The primary goal of the surgery is to remove cancerous tissue and prevent its spread throughout the body.
